Application filed September 28,

This invention relates to improvements-in sealed receptacles.

Receptacles now in taining food ordinary use for conof various kmds areplaced on shelves or in refrigerators in close proxor. odors of t whichis very 1 the strength and flavor of the food imity to each other.

, Food within the receptacles is very apt to absorb the flavors cles,more, is often lost time.

It is one of vention to overcome objectionable receptacle in he food inadjacent rece taobjectionable. Furt erwithin comparatively a short theobjects of the present inthe above mentioned features and provide aseale which the food may be placed and the cover sealed thereon in avery simple manner.

A further object of the invention is to provide a sealed receptaclewhich may be used in an inverted position and in which the cover mayalso be used in position.

A further provide a sealed receptacle having means for an invertedobject of the invention is to easily sealing the joint between thereceptacle and its cover in either position 0 use.

A further provide a sealed receptacle ceptacles may in a manner to besition.

A further the invention is to in which the rebe stacked one above theother safely maintained in poobject of object of the invention is toprovide a sealed receptacle which is of simple construction, is strongand durable, and

is well adapted for the purpose described.

In the accompanylng drawing,

' in which thesame reference characters indicate the same parts in allof the views:

surface of the flange is of reversed curved formation in cross sectionto provide a sealmg groove 11 and a ridge 12, entirely around the upperedge of the rece tacle.

groove 11 extends around the ri ge 12 and is entered by the rounded edgeportion 13 of the cover 14 which closes the receptacle. The crossdiameter of the said rounded edge 13 is less than the cross diameter ofthe curve of the groove to form sealing spaces 1 1 therebetween. Theedge portion of the cover is also formed with a groove 15 to receive therid e 12 to provide a double contact and a .dou le seal between thecover andthe receptacle. As the upper edge portion of the cover is alsoformed with the rounded edge and groove 13 and '15 of the same shape asthe lower edge, the

cover may be used in inverted positionon the receptacle. Said cover isalso formed on one side with a raised part 16 and on its 0 posite sidewith a depression 17, so that t e cover may be used as an independentdish when desiredto hold or discharge moisture from the receptacle. Whenused Fig. 2, the moisture will flow moisture will be retained in thedepressed portion of the cover. The surfaces of the opposite sides ofthe cover are formed with rooves and ridges 18 and 19 extendin at 3 topermit circulation of resting on the cover. The grooves and rid es alsoprovide; for any moisture within t e rece tacle flowing from the grooveson one si e into the sealing spaces 14 when the receptacle and cover areused in the position shown in Fig. -.2.

The inner and outer sides of the bottom portion 20 of the receptacle arealso proridges 21 and 22, e or cover is the as shown in Fig. air beneathfoo so that when one receptac placed above or stacked on the other,

-' simple construction,

' table and having an edge Etl ' cover is placed on the points, and alsohaving grooves and ridges willinterfit as shown in Fig. 2, and the partswill be firmly held in position without liability of slipping.

When the receptacle is used in an inverted position as shown in. Fig. 2,the groove 15 will be entered by the ridge 12 and the spaces 23 willform a double seal when filled with: water.

In use it is only necessary to place the article of food in thereceptacle and then our water in the grooves to seal the joint etweenthe coverand the receptacle. both the receptacle and the cover areinvertible, the parts may he used either side or end up and also usedseparately. From the foregoing description it will be seen that thesealed receptacle is of very and is well adapted for preventing foodfrom absorbing odors from adjacent material and also for maintaining itsown flavor and moisture intact, and thus better preserving the food.
